WAXlING DEVlCE FOR WAX-THREAD SEWING-MACHINES.

SPECIFICATION forming part of Letters Patent No. 399,578, dated March12, 1889.

Application filed October 25, 1887- Serial No. 253.339- (No model.)

To (all who/n if; 71mg (1417100771.:

Be it known that I, EDWARD A. SrieoINs, a citizen of the Don'iinion ofCanada, and a resident of .Ilrockton, in the county of Plymouth andState of lllassaehusetts, have invented new and useful lm provements inWaxing Devices for ax llhread Sewing-Machines, of which the following,taken in eoiiineetion.with the z'tccompanying drawings, is aspecification.

This invention relates to improvements in waxing devices tor wax-threadsewing-machines, and it is carried out as tollows, reference being hadto the accompanying draw ings, wherein, V

Figure 1. represents a front elevation of the invention, showing aportion of the wax-tank, as well as a portion of the steam-chamber inthe horn, in section. Fig. 2 represents a side elevation of theinvention, showing the stationary 't'rames in section. Fig. 3 representsa crosssection on the broktm line 1. l in Fig. 1. Fig. 4: represents ahorizontal section on the line 2 2 in Fig. 1. Fig. 5 represents ahorizontal section on the line :3 3 inFi 1. Fig. (3 represents avertical section on the line l -.t in Fig. 5. 7 represents across-section on the line 5 5 in. Fig. 5. Fig. 5 represents across-section. on the line 0 (.3 in Fig. Fig. 0 represents a horizontalsection on the line 7 7 i n Fig. l, and Fig. 10 represents a centrallongitudinal section of the wiper or scraper for removing the surpluswax from the thread after being waxed.

Similar letters refer to similar parts when ever they occur on thedififerent parts of the drawings.

a and l) represent the upper and lower portions of the sewing-machineframe, in which is journaled the vertical post 0, that is provided inits upper end with the bent horn c, as is in common in wax-threadsewing-machines. The post 1: made hollow, as usual.

To one side of the horizontal 1; ortion of the horn c is secured thewax-tank (I, which is surrounded on its sides and bottom with a closedsteam-jacket, (1, through which steam is caused to circulate for thepurposeof heatingthc wax, XV, contained within the tank (1, as shown :inFigs. 1, 2, and 3.

e is the steam-suppl pipe entering the upper portion. at thesteam-jacket d, and connected to the pipe e, that is secured to the post0 below its bearing a, as shown in Fig. 1. f is a similar pipeleadingfrom the lower por tion of the steam-jacket d to the pipej, thatis also secured to the post (3 below the hearing a, and serves as asteam return-pipe, as well as a condensed-water return-pi ie for thejacket d, so as to establish a proper circulation of the steam throughthe j aeket d.

To the frame h secured in a suitable manner the annular cup g, throughthe cen tral vertical perforation of which passes loosely the lowerportion of the post 0. In the bottom of the cup r are made two annulargrooves, g and g, (shown in Figs. (3, 7, S, and 5),) the former beingconnected to the steanrsupply pipe E, leading from any suit able sourceof steam-pressure, and the latter being connected to the drip, return,or exhaust pipe F, as shown in Figs. 5 and .l. E and F are valves orcut-oll'fs on the respective pipes E and F, as shown in Figs. 1, 5, and9.

\Vithin the cup 9 is arranged the annular ring 72, made of metal andhaving its under side ground or finished. to lit steam-tight against thebottom of the annular cup g, as shown in Figs. (3, T, and 8. On theunder side of the ring 71 are made annular grooves 71 and 71, arrangeddirectly opposite the respective grooves g and 5 in the bottom of thecup 5 as shown in said Figs. (5, 7, and 8. The ring 7t is held againstthe bottom of the cup {1 by means of annular packing rings or glands i7;, that are screwed into the interior sides of the inner and outer wallof: the cup 9, respectively, as shown in said Figs. (3, 7, and S, andsuit-able packings are interposed between the under side of the annularglands i 7; and the enlarged lower portion of the ring 7z,as shown insaid Figs. 0, 7, and 8. The lower ends of the pipes ef are screwed to orotherwise firmly secured to the ring 71, as shown in Fig. (1, therebeing in the said ring two perforations or channels, 72 and h, theformer connecting the steam-supply pipe 6 to the annular grooves g and72 and to the steam-supply pipe E, and the latter connecting the return-)i )e to the rooves r it and to the return or drip pipe F, as shown inFig. 6. The post 0 being secured to the pipes e f, and the latter beingsecured to the ring h, it will be seen that the latter partakes of themotion of said post 0 when it is turned around its axis; but to preventundue strain on said pipes e f during such turning of the post 0, Isecure to the latter a flange or collar, 1, hav ing forked or perforatedprojections or ears 1' l, into which are fitted pins or projections llII, secured to the ring h, as shown in Figs. 1 and 5.

it will thus be seen that by the arrangement and combination of parts asabove described the post 0 may be turned completely around its axis in'its bearings a 17 without breaking the connection between the stationarypipes E F and the corresponding movable pipes e f, thus insuring at alltimes a proper circulation of steam in the jacket d for the properheating of the wax in the tank CZ.

On the top of the wax-tank d is arranged the cover 01, which may behinged to said tank or otherwise secured temporarily in place on top ofthe said tank, as may be most convenient and practical.

On top of the post 0 is located the cup or receptacle 0 for the ball ofthread M, from which the thread m to be waxed is carried, by means ofthe guide 0 secured to the cup 0, into the molten wax in the tank d, andthrough the hook or eye (1 within said tank (l upward through the wiperor scraper N, that is secured to the top of the tank (Z or the horn c,and said wiper serves the purpose of removing from the waxed thread thesuperfluous wax. The said viper consists of the hollow cylinder N,having arranged within it the perforated ball 41, preferably made ofrubber, which ball is kept in place within said hollow cylinder N bymeans of the hollow cylinder or sleeve 01, that is screwed through therear portion of the hollow cylinder N, as shown in Fig. 10. The waxedthread m, after passin g through the wiper N, is conducted around andbetween the tension-rolls O to the top of the horn c in the usualmanner, said tension disks or rolls being constructed as is usual inwax-thread or other sewing-machines; but during the passage of the waxedthread m from the tension-rolls to the whirl at the top of the horn c itis very essential thatthe waxed thread should be prevented from cooling,so as to obtain the best results in doing the work, and for this purposeI arrange within the horn c a hollow chambered arm, P, the lower end ofwhich is pivoted to a pro jection, D, of the wax-receptacle (Z in thesame manner as gas-brackets are pivoted to their connections, (see Figs.1, 3, and 4,) said proj ection D having an interior bore or channel, D,in open communi zation with the steamjacket ('1', as shown in Fig. 3, bywhich the steam from the latter is communicated to the interior of thehollow chambered arm P, in close proximity to which the thread m iscarried on its way from the tension-rolls O to the Whirl at the top ofthe horn c, and by which arrangement the waxed thread is kept soft andpliable. The arm P is pivoted to the projection D on the wax-chamber clto enable said arm to be swung out of position to reach the connectingmechanism for the whirl, that is arranged, in the usual manner, withinthe inclined portion 0' of the horn of the machine, for repairing thesaid connecting mechanism or for other purposes. The hollow arm P issecured in place to the horn c by means of a spring-pressed button, 19,spring, screw, or equivalent or well-known device.

Having thus fully described the nature, construction, and operation ofmy invention, I wish to secure by Letters Patent, and claim 1. Thecombination, with the post and horn of awax-thread sewing-machine, ofajacketed wax-tank, the stationary cup g, having inner and outer annulargrooves, the rotating ring h, having inner and outer annular grooves andvertical pins or project-ions H, the pipes and f, leading, respectively,from the grooves to the jacketed tank, the pipe E, leading from a sourceof steam-pressure to the inner grooves, the drip leading from the outergrooves, and the collar Z, secured to the post and engaging the pins orprojections 011 the ring, substantially as described.

2. The combination of a jacketed wax-tank, a bracket, D, having thechannel D communicating with the jacketed tank, the horn c, thechambered arm P, pivoted to the bracket and communicatin g with thechannel therein, and a steam-supply for the tank, substantially asdescribed.

In testimony whereof I have signed my name to this specification, in thepresence of two subscribing witnesses, on this 20th day of October, A D.1887.
